Which electromagnetic waves have the highest frequency? Chemistry Bohr Model of the Atom Transverse waves. Daniel W. Jan 19, Explanation: There are seven regions in the electromagnetic spectrum which in order of lowest to highest frequency are: Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.

Wireless routers use light to send pictures of cats from the internet to your computer. Car radios use light to receive music from nearby radio stations. Even in nature, light carries many kinds of information. Telescopes are light collectors, and everything we know from Hubble is because of light. Since we are not able to travel to a star or take samples from a faraway galaxy, we must depend on electromagnetic radiation — light — to carry information to us from distant objects in space.
The Hubble Space Telescope can view objects in more than just visible light, including ultraviolet, visible and infrared light. These observations enable astronomers to determine certain physical characteristics of objects, such as their temperature, composition and velocity. The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see.
In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes. All light, or electromagnetic radiation, travels through space at , miles , kilometers per second — the speed of light.
Light travels in waves, much like the waves you find in the ocean. As a wave, light has several basic properties that describe it.
One is frequency, which counts the number of waves that pass by a given point in one second. Another is wavelength, the distance from the peak of one wave to the peak of the next. These properties are closely and inversely related: The larger the frequency, the smaller the wavelength — and vice versa. Each section of the electromagnetic EM spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons.
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation , visible light, infrared radiation, and radio waves.
Microwaves like the ones used in microwave ovens are a subsection of the radio wave segment of the EM spectrum.
